    copied!<p>The gradient effect is possible using the free version of <a href="http://www.visiblox.com" rel="nofollow">Visiblox Silverlight Charts</a>. See the example application 'Hindsight' to see how Visiblox charts can be applied to an application of this context.</p> <p>I've attached a crude code snippet of the XAML on how to achieve this effect:</p> <pre><code>&lt;UserControl x:Class="SilverlightApplication1.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:v="clr-namespace:Visiblox.Charts;assembly=Visiblox.Charts"&gt; &lt;UserControl.Resources&gt; &lt;LinearGradientBrush x:Key="GradientBrush" StartPoint="1.0, 0.0" EndPoint="1.0, 1.0"&gt; &lt;GradientStop Color="AliceBlue" Offset="0.3" /&gt; &lt;GradientStop Color="DarkBlue" Offset="0.7" /&gt; &lt;/LinearGradientBrush&gt; &lt;/UserControl.Resources&gt; &lt;Grid x:Name="LayoutRoot" Background="White"&gt; &lt;v:Chart x:Name="Chart"&gt; &lt;v:Chart.Series&gt; &lt;v:LineSeries x:Name="Series" ShowArea="True" AreaFill="{StaticResource GradientBrush}"/&gt; &lt;/v:Chart.Series&gt; &lt;/v:Chart&gt; &lt;/Grid&gt; </code></pre> <p></p> <p>Personally, I would take the action that Hindsight does, removing the area under lines when there are multiple series on the plot area. I think at that point the gradients get in the way of the data, and as you mentioned above, to do something about this incurs a computational cost. This could also lead to misinterpretations of the data so be wary.</p> <p>In terms of getting your data to the chart, you can use the Visiblox BindableDataSeries to bind your business objects directly onto the chart. :)</p> <p>Disclosure: I have previously worked as a developer on Visiblox Charts.</p> <p>Hope this helps!</p>
